Hi everyone, Is there a way to tell by looking at it, if this motor I am working on has been converted to 15HP, would the cam's look diferent or have any markings?
The motor I am working on is a 96 9.9 2stroke

If it's a M 9.9 D2 have same CC and same carb as 15 model, 9.9 has different throttle cam shape though, cam is shorter than 15 model, will need to change it and advance + 5? timming to have 25? as this model is adjusted to 20? and won't ever go into full throttle/180? butterfly openning.

Happy Boating

Thank You Sea Rider, I was born in Lima used to surf La Pampilla! Now in California.
My question was... Can yo tell by looking at the cam if it's the shorter one? Anyone has pictures of both? Or is there any markings on the Cam itself to tell if it has been upgraded to 15HP

Hola Imaster,

Welcome on board, see pic, 15 cam has an angle at left end 9.9 is more eliptical at end. Or post a pic of your actual cam to check.

Happy Boating

Hi Sea Rider,
I know these are not the best pics, I will go to the boat tomorrow and get better ones, but maybe this is enough to see, these where taken when I got the motor.

It's the original 9.9, change for 15 HP part N? 364-63718-0 will be same as first pic posted. You can ask Pvanv or Internet Outboards to quote and ship you one.
